tact on'the end ofthe bolt43 with'very little more or less porous, theseconduits are llined' with a tube 47 of diii'erent:material, such asbrass.

The 4crank shaft 18lis also drilled. out,

forming conduits 48, leading to the connectin rod bearings, and a smallpipe or conduit 49 leads from the lower connecting rod gles to eachother, the present cam shaft havmg seven bearings, and the holes beingarranged equi-distant, as shown particularly in Fig. 3. One of the'holes'is shown in full.

bearing 24 -to the piston pin bearing 25.`

Also at its main bearings, the crank shaft has radial holes 50, whichare adapted to register at each revolution with the respective conduits46, so that oil supplied under pressure to the said conduits 46 willenter the crank shaft main bearings and be distributed to them bycircumferential rooves 51, and any excess of oil will pass `t rou h thehole to the interior of the cranksha from thence to the connectingrodbearings 24 through conduits 48, and from thence to the piston pin 26through conduits 49.

.Of course it will be understood that oil will be squeezed out throughall of these bearings during the operation of the motor, and will bethrust from the various revolving and reciprocating-` arts and collectedat the bottom of the cran case in the sump formed by the bottom cover11. y f It has beenshown above how oil is supplied to. the interiorofthe cam shaft 28' under pressure, and upon reference to Figs. 1 and 3,itwill be seen that the cam shaft is provided with a radial hole 52 ateachv of its bearings, these. holes being arranged at anlines,`and five-of them -in dotted lines, the seventh hole'is omitted because ythe lineon I lwhich Fig. 3 is taken is at the rear of the forward cam shaftbearing..

It will be-understoodthat each of these holes 52 registers during eachrevolution/of the cam shaft with its rrespective'conduit 46, so that oilunderpressure is distributed byA means of the cam shaft 28 to thevarious conduits 46 in succession, not more thanone conduit beingsupplied'v ata given time, so

that the pressure is'niaintained in the distributing cam shaft.

One of the advantages of this method of distribution is that should oneof the crankv shaft'bearings become loose,so that the oil l wouldreadily leak through it, the other Y bearingls) would-still receivetheir full 'uot'a of oil, y reason of the fact that the oose bearing 1sconnected with the distributing 'cam shaft at intervals only, and notsimul- 'taneeusjly with 'any' of the other shaft at the extreme rear endof 'the cam shaft, so 'that' the pressure within the cam shaft is thepressure registered, the ,oil being supplied to the `extreme forward endof the cam shaft. This is of considerable advantage tothe operator inthat he is always aware of the minimum pressure within the oilingsystem. v

In Fig. 1 the oil pump 53, may be seen 1n elevation as secured to thes1d e of the crank case 10, as bybolts 54.- A pipe 55 leads from thebottom of the crank case or sump to the intake side of the pump, and thepi e 34, hereinabove described, leads from t e pump to the forwardbearin s 27 of the cam shaft, where the; oil is carried tothe interiorof thecam shaft by the groove 32 and holesA 33. Another pipe 56 leadsfrom the delivery end of the 'pump to anydesired auxiliary ystem, nonebeing. shown *Trng-the drawings.

' 'The oilpump'is particularlyillustrated: J in Figs.' 4, 5 and 6, andconsists of acastxs' metal-body, faced oi at'57to ttheycrankcase 10, andprovided with a boss 58 extend ing into the crank^case and surrounded-by a spring-59 controlling 'a pump plunger 60. g' This plunger 60' isthusv spring pressed' against a 'cam or eccentric 61 formed on the.,cani shaft 28. The plunger-60 operates the bored out cylinder 'portion62 :ofthe-'1 pump and the valves 63 andA 64.control the j 'l intake andoutlet respectively, of the pump. f; The pump is further provided with'acon-' '105g trol valve in the form of a piston 65 "slidigj uy haaagainst the stop 67 by spring 68. When the piston is inthe positionshown the draw.-

ings, it closes entirely the outlet ports Y'69 and '69l of. the vpump',but'^fa slight il :against the piston raises it and permits the oil toescape, and a greaterfpressurecauses :the piston to rise farther `andexposes the 'overiiowport 70, which returnstheexcess ina cylindricalcasing 66 and norm oil to the crank case, as. will be Seen partic- Inthe pump bod cylindrical casing 72, in which is supported ularly'inFig.4. Another overflow passage v71 is provided. above'the piston'65 for re.

turningto the' crank case anyoil that may escape past the piston.'

12o y there is also formed a s a screen or strainer-73, through whichthe oil must pass toA reach 'thepump. A passage 74 leads from the 1cylinder portion A7 2 to the intake valve 63 of the pump. There 1s"Aalso 'a' passage 75 .leading vertically thrpugh-the pump body tothetop-ofgthe cylinder portion 72. Y Thus the oil will pass from theintake vpipe 55,'through the pm-ge and cleaning.

.75 to the strainer 73; andthrough the-cylinder portion 72 and passage74, to the intake valve 63; thence through the pump and outlet valve 6i,tov the outlet port 69 and 69, passage 34B, and pipes 34 and 56.

It will be seen that all of the parts of the pump are readily removablefor inspection Having thus described my invention, what I claim and.desire tov secure by Letters Patent,'is't v 1 Y l.
